1 Claim.

This invention relates to metal weather stripping for steel casementwindows and doors. It is particularly directed to weather strippingwhich may be applied to steel casement windows 5 or doors, and whichwill grip the same without the use of nails, screws or other attachingmeans, or the necessity for drilling holes.

An object of this invention is to provide a durable and relativelyinexpensive weather stripping which shall be easy to apply, which willpositively prevent drafts, and insure a thoroughly weatherproof.construction when the sash is closed, and which is neverthelesspractical and eflicient to a high degree.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts which will beexemplifled in the construction hereinafter described, and of which thescope of application will be indicated in the following claim.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments of this invention,

Fig. 1 is a front, elevational view of a steel casement window providedwith weather stripping, embodying the invention, and with parts incross-section;

Fig. 2 is a cross-sectional view taken on line 22 of Fig. 1;

Fig. 3 is a partial, front View of the casement window in closedcondition; and

Fig. 4 is a perspective View of a piece of the improved weatherstripping.

Referring now in detail to the drawing, I0 designates a building wallprovided with a usual metal window frame I Bolted to the frame I, as bybolts I2, is an inner metal casement frame I4. Said frame M has top,bottom and side walls l5, perpendicular to the plane of the buildingwall.

' Extending inwardly from the walls l5, and disposed-on the inside ofthe window, are top, hottom and side flanges l6, disposed in a commonvertical plane. There also extends outwardly from the walls l5, at theoutside of the window, flanges located at the top, bottom and sides ofthe window and contacting the outside of the building wall.

The flanges I! carry brackets M3, to which is pivoted a window sash 20.Said sash 20 comprises a metal sash frame 2| having top, bottom and sidewalls 22 disposed parallel to and in- Wardly of. the walls l5. Extendingfrom the walls 22, on the inside of the window, are flanges 24 adaptedto substantially contact the flanges I3 of the frame l4. Extendingoutwardly from the walls 22, and disposed at the outside of the window,are flanges 25 adapted to overlap the flanges 5 IT. One of the flanges25 carries brackets 26, pivoted as at 21 to the brackets l8.

The casement frame and sash described are of usual and well knownconstruction. The weather stripping 30, embodying the invention, issecured 10 in suitable lengths, at the inner edges of the flanges It, asshown in the drawing. Said stripping 30 may be made of usual resilientmetal weather strip material, such as stainless steel or the likematerials. 15

The same comprises a flat Wall 3|, about onehalf inch in width, andextending at right angles, and to one side of the plane thereof, is wall32 about one-eighth of an inch in width. Extending from the wall 32 is awall 33, parallel to the wall 20 3| and of substantially half. the widthof said latter wall, forming a groove 34 therewith. Ex-

tending from the wall 33, inwardly, into the groove 34, is a narrow lip35. It will be noted that the lip 35 is inclined toward the walls 3| 25and 32.

Extending from the wall 3|, to the other side of the plane of said wall,is a wall 38, likewise about one-half inch in width and at an angle ofsomewhat less than ninety degrees thereto. Ex- 30 tending from the wall38, at an angle of somewhat more than forty-five degrees, and toward thewall 3|, is a wall 43, likewise substantially about one-half inch inwidth and terminating short of said wall 3|. 35

Extending from the wall 4!), toward the walls 38 and 3|, is a short wall42, spaced from the wall 3|. The wall 42 is normally inclined toward thewalls 38 and 3|, and extending therefrom is a relatively narrow lip 43,inclined somewhat 0 away from the wall 3|.

The weather stripping 30 is applied to the flanges l6 of the inner frameM by inserting the flange into the groove 34 with the wall 33 of thestripping 30 on the inside of the window, and the 45 wall 3| contactingthe outer surface of said flange.

It will be noted that the walls 38, 40, 42 and 43 of the stripping aredisposed between the walls I5 and 22 of the inner frame l4 and thewindow 50 sash frame 2|, respectively. Upon closing the window sash, thesame is adapted to engage the wall 40 and resiliently press the wall 42against the adjacent surface of the wall 3|.

The flange 24 of the easement window con- 55 tacts the wall 3| of theweather stripping and presses the same against the flange I 6 of theinner frame M. The Weather stripping secures itself to the flange l6 dueto the engagement of the lip 35 with said flange upon mounting the stripthereon.

It will be noted that the wall 42 resiliently contacts and pressesagainst the sash frame 2! when the sash is closed, to prevent draftsfrom entering the house. It will be understood that the weatherstripping may also be applied to casement doors.

If desired, however, the weather stripping may be fastened to the flangeiii of frame [4 by any suitable fastener as at 140..

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

Weather stripping made of thin resilient sheet metal comprising a wall,a second wall extending to one side of the plane of said first Wall, atright angles thereto, a third wall extending from said second wall,parallel to the first wall, and forming a groove therewith to receivethe flange of a casement frame, a fourth wall extending from the firstwall to the other side of the plane thereof, a fifth wall extending fromthe fourth wall toward the first wall, at an angle to said fourth wall,a sixth wall extending from said fifth wall toward said fourth wall andadapted to engage said first wall, and a lip extending from said thirdwall into said groove and being inclined toward said first and secondwalls.
